Review: Smaller than original but works great - I ordered this ballast for a standard T8 (1" diameter lamps) fluorescent fixture that didn't work. None of the bulbs showed any sign of life but I had input voltage. Replacing the ballast was easy. Turn off the breaker or switch to the fixture. Disconnect the input wires (black and white) and cut the rest of the wires near the ballast. Remove the old ballast and connect the red, blue, and yellow wires using wire nuts designed for 16-22 ga. wire (usually colored blue and not included). The wires are solid and need to be pretwisted before putting on the wire nut which can done with any pliers. The wire nut alone will not properly connect the wires. There is no polarity for the colors and can be connected either way as long as the colors match. Now hook up the supply lines and reassemble.
Review: Worked for me - Well, I have a 4 tube light in the kitchen. I'm installing replacement doors on the cabinets, and one morning the light didn't come on. I need to see what I'm doing. Pulled the light switch and it was good. Put my meter leads in the old wire nuts in the light fixture and it was getting power. I immediately ordered this replacement. It came fairly quickly. Easy install: the base/mounting fit the mounting points in the light housing in the same position. The lines were more than long enough, in fact I had to trim them down to fit just right. Light works fine now. Don't hear any noise from the transformer/ballast. Also a lot cheaper than the other options. Got no complaints.
